Verbena plant named ‘Amarena’

ABSTRACT

A new and distinct variety of  Verbena  plant particularly distinguished by its deep red flower, early flowering and a habit that is first semi-erect and later spreading.

Latin name of the genus and species of the plant claimed: Verbena hybrid.

Varietal denomination: ‘Amarena’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new distinct cultivar of Verbena, botanically known as Verbena×hybrida.

The new cultivar is propagated from cuttings resulting from the cross of ‘B742’ and ‘B728’. ‘B742’ is a scarlet flowering Verbena having a spreading habit. ‘B742’ is not commercially available and is not known by any synonyms. ‘B728’ is a deep rose flowering Verbena having a semi-erect habit. ‘B728’ is not commercially available and is not known by any synonyms. Neither ‘B742’ or ‘B728’ has been patented.

As a result of this cross the present cultivar was created in 2000 in Enkhuizen, Netherlands and has been repeatedly asexually reproduced by cuttings in Enkhuizen, Netherlands and Sarrians, France over a three year period. It has been found to retain its distinctive characteristics through successive propagations, and this novelty appears to be firmly fixed.

This new Verbena plant is an annual in most climatical zones in the US, only in zones 9 and 10 it is a perennial plant.

DESCRIPTION OF THE DRAWING

This new Verbena plant is illustrated by the accompanying photographic drawing which shows blooms, buds and foliage of the plant in full color, the color shown being as true as can be reasonably obtained by conventional photographic procedures.

DESCRIPTION OF THE NEW CULTIVAR

The following detailed descriptions set forth the distinctive characteristics of this new Verbena. The data that define these characteristics were collected from asexual reproductions carried out in Enkhuizen, Netherlands. The plant history was taken on 14 weeks old plants, blossomed under natural light in a greenhouse and grown in a 10.5 cm container. Colour readings were taken in the greenhouse under ambient light. Colour references are primarily to The R.H.S. Colour Chart of The Royal Horticultural Society of London.

The commercial name of the most resembling variety is ‘Babylon cherry red’. The patented name of this variety is ‘Charmena’ and its U.S. Plant Pat. No. is 11,134.
